I worked really hard on a project and my boss was unhappy with the result. She decided to go with a different direction, which means my team and I have to start over. I feel like I failed and the blow to my ego has been difficult to handle. I don’t like disappointing people. I notice myself feeling less confident as we move forward with this project and even in my daily interactions at work. How do I rebuild my confidence at work and learn to pull away some of those attachments/emotions?
